[IMP](selection) Added some tolerance on the visual elements' bounding boxes to make it easier for the user to select very crowded areas.
[FEAT](pvc.color.isGray) New utility method.
[FEAT](MetricPoint HeatGrid Colors Sizes) The handling of color and size scales and presentation is now the same (or almost) between these two charts (for example, the HG now also shows negative size values in ABS scale mode with a dashed border).
[FEAT](Pie Linked) Link lines and labels are now also grayed out when not selected and there are any selections.
[FEAT](ValuesMask - Bar family, Point family, MetricPoint family, HeatGrid) Added the values mask option to these chart types. Documented.
[FEAT](ValuesAnchor HeatGrid) Added the missing option. Documented.
[FEAT](NullShape MetricPoint) Added the missing option. Documented.
[CHG](ColorAxis ColorMissing) Changed the default value of this color from "#efc5ad" to "lightgray".
[CHG](tipsy) Log level changed from 4 to 20.
[FIX](SizeAxis options) The size axis options were only accessible through the "size" prefix, instead of the intended and documented "sizeAxis" prefix.
[FIX](Axis hierarchical label trimming) Label trimming was not accounting for the trim indication '..' length. This caused labels to overflow into the plot area and interfere with rubber-band selections in this area.
[FIX](error logging) Chart errors had the prefix "[pvChart ERROR]: " added multiple times, in errors occurring inside protovis.
[FIX](NoDataException) Error that occurred while trying to updateSelections when the chart has no data.
[FIX][DOC](HeatGrid valuesVisible) The option's default was incorrect.
[FIX](protovis pv.Line pv.Area smart segmented mode) A bug caused by sharing the same parent group for the visible segment paths and for the invisible/events unit-segment paths.
[FIX](protovis Color brighter darker) Some calls weren't respecting the call interface of not specifying optional arguments. Changed the argument passing detection to test for != null.
[FIX](protovis pv.Dom.Node insertAt) The inserted node's previousSibling property was not being assigned.
[FIX](protovis IE window.getComputedStyle) Missing method error.
[FEAT](protovis pv.Mark. getShape) Added new argument, 'inset', to allow to obtain a slightly deflated shape for accounting for users' non-precise selections.
[REF](protovis pv.listener IE) Integrated MSIE's listener related code into the main protovis' methods.
[FIX][PERF](protovis pv.Mark renderCore) The stack was being populated with elements already in the stack.
[FIX](protovis Marks effective scale) The effective scale factor was not being updated on the context mark, but only its children was.
